Describes what is customary in the market for sales and customer support.
Last Published: 7/12/2018

After-sales service and customer support are important components of a sale; purchasers of foreign products will expect access to a local provider, rather than from a regional base. This is especially true for State Owned Enterprises or government customers. Foreign firms should invest in customer service training for front-line local sales staff, as well as training for technicians.

Warranties are also an effective marketing tool to assure customers that they are buying a genuine, high-quality product. Foreign (offshore) suppliers are generally not permitted to directly provide after-sales service and customer support unless they have a licensed foreign investment project in Vietnam. Otherwise, a Vietnamese company must provide these services.
